WIND-GUARD 7 FOR AUTOMOBILES.

Specification of Letters Patent.

Patented Dec. 15, 1914.

Application filed September 15, 1909. Serial No. 517,885.

To all whom it may concern n Be it known that I, STEWART BROWN, a citizen of the United States, residing at the city and county of San Francisco and State of California, have invented certain new and useful Improvements in Wind GuardS for Automobiles, of which thefollowingis a specification.-

The hereinafter described invention relates to that class of wind guards commonly ,termed wind shields, designed for attach 1 ment to the front of the car for protecting the driver against the direct effect of the wind, and more particularly to. that type wherein one section ofthe guard is mounted relative to the opposing section so as to be swung over on its pivotal points.v Usually,

the swinging section of the guard is held in.

adjusted position by means of thumb nuts, which have to be released in order to per mit of the driver swinging the :same relative to the fixed or non-movable section. When the car is driven at a high rate of speed, it is somewhat difficult for the driver thereof to reach overfor releasing the thumb nut, either for tightening or loosening the swinging section of the wind guard or shield.

The object of the present invention is to provide an automatic lock connection between the fixed and swinging sections of the wind guard, which will give under the influence of pressure exerted on the swinging section by the driverof the car to permit of the same being thrown into desired-position, the holding of the lock means being sufficient to overcome the wind pressure against the surface of the swinging section of the guard during travel of the car; the connection between the frames ofythe guard sec .tions being such as to confine the movement of the swinging section to one direction, as for instance inwardly, so that the said sect1on is held against movement in an opp0 site direction should the driver of the car. place an outward strain thereon while entering or leaving the car.

To comprehend the invention, referenceshould be had to the accompanying sheet of.

drawings, wherein V Figure 1 1s a broken side elevatlon of an automobile with the improved Wind guard applied thereto. Fig. 2 is a detail side view of the male member of the lock joint for the swinging section of the wind guard. Fig.3 is asimilar view of thefemaleqmenr ber of the 100k joint. Fig. i is a detail plan view of the lock joint, t-heboss within which the compression is located being sectioned.

In the drawings, the numeral 1 indicates the metallic frame for the lower immovable section 2 ofthe wind guard, which'is rigidly secured to the front oft-he car 2, in the present case, 'bythe brace rods 3. To the sides of the frame 1 adjacent the upper ends thereof, the lock members 4 are held thereto by the brackets 5, thesaid lock members beoutwardly projecting flanged Within the periphery of the, flange :6 of the male lock members 1, a series of seats 7 '7 are formed,

and each hinge or lock member 4 is provided with an outwardly projecting stud or ,ing of circular form and provided with an trunnion 8, on which swing the lockmem bers of the upper section of the wind guard. The metallic frame. 9, of the upper sec tion 9 of the wind guard isprovided at its sides, adjacent the lower ends thereof, with. the lock members 10, held thereto by the bracket pieces 10, and the said lo'ck memhere, like the lock memberst, are circular in form and carry the inwardly projecting flange 11, of a diameter slightly greater than that of the circular flange 6 of the loclcmember 4 over which it fits. Onthe inner face of the lock members 10, a plurality of raised cam projections 12 are formed, adapted to register with the seats 77 of the lock members 4, within which they seat, when the lock members 10 are turned. sothat the seat cam projections 12 .register therewith, The lock members 10 are mounted on the studs or .trunnions 8, when the parts are assembled and turn thereon as pressure is applied to swing the upper section 9. :Onto the trunnions 8 are loosely fitted the enlarged heads or bosses 13, of the brace rods 3, which bear against the outer. face of the lock members 10 and exert an inward pressure thereon to hold the sameinto locked engagement with the lock members 1, due to the pressure of the compression springs 14, interposed between the said heads or bosses and the securing.

9' of the wind guard, that when the same,

is swung into a vertical position to the lower section 2, the ends of the frames 1-9 abut, and the swinging movement is arrested, in fact, the said swinging section is held locked against further outward movement, in case the wind guard is mounted for an inward ment, separating the lock members 10 laterally to an extent equal to the height of the I projections 12 and raising the upper section of the guard so that the ends of its frame will clear the ends of the frame of the lower section during the swinging-movement. As I the cam projections 12 come into registry with the seats 7 of the fixed lock members 4, the tension of the springs 14 force inwardly the lock members 10, so asto place the cam projections 12 into locked engagement with the seats 7 and hold the upper section of the wind guard in the desiredadjusted position. Inasmuch as the lock members are held in tension by the lateral strains of the compression springs 14, the same are positively held against displace- I ment by the vibrations of the car while in action; a strong and eflicient locking of the interlocking members 4-10 being thus obtained, which would not result in case thelock members were held together by spring actuated securing pins held in one member engaging peripheral seats formed in the inner face of the rotatable member.

The locking member 4 is provided with a central annular boss 4, and the cooperating member with a boss 10, the latter being of larger diameter than the former, and adapted to have a sleeved engagement therewith, whereby to form a central pivotal bearing s between the members, tending to strengthen the parts and to reduce friction in the adjustment thereof, The bosses 1 and 10 also form an eXtended bearing for the bolt 8, therebytending to reduce the strain on this part and prevent canting of one mem her relative to the other, which might tend to interfere with the ready adjustment of the same. It will also be noted that the peripheral edge of the flange 11 is continuous and unbroken and that this flange overlies the flangeof the cooperating member, to the end that the locking means is wholly confined in the housing provided by the members themselves, thereby largely protecting against the action of moisture without the necessity of an auxiliary casing for this purpose.

Having thus described the invention what lea-sable to permit the members to be adjustis claimed as new and desired to beprotected by Letters Patent is- 1. In a hinge construction for automobile wind shields or guards, the combination of two cup-shaped members, one having a slightly smaller diameter than the otherv and the periphery of the flange of one member overlying the periphery of the other flange and forming a housing therefor, the flange of the inner member having in its free edge one or more recesses, and the flange of the inclosing member having a continuous unbroken edge and one or more lugs proj ecting inwardly from the periphery thereof at substantially right angles to the flange, and spring means for holding the lugs in' holding engagement with the recesses, said means being releasable to permit the members to be adjusted by a relative rotary movementj I 7 2. In a hingeconstruction for automobile wind shields or guards, the combination of two cup shaped members one having a slightly smaller diameter than the other, and the peripheral flanges of the members having a sleeved engagement, the flange of the inner member having in its freeedge one or more recesses, and theinclosing member having one or more lugs projecting inwardly from its flange at'su'bstantially rightangles to the latter at a point intermediate the edge and the base of the flange, spring means for holding the lugs in locked engagement with the recesses, said means being'reed by a relative rotary movement, and auxiliary inwardly projecting annular intersleeved bosses. on the members forming a gentral pivotal bearing between the memers.

3. In a hinge construction for automobile wind shields or guards, the combination'of two cup shaped members one having a slightly smaller diameter than the other, and the peripheral flanges of the members having a sleeved engagement, the flange of the member having in its free edge one or more out out parts forming recesses, and the inclosing member having one or'more lugs projecting inwardly from its flange intermediate its edges at substantially right angles to the latter and of a length to extend beyond the inner periphery of the cooperating flange, auxiliary inwardly projecting annular interengaging bosses on themembers, 'a centrally arranged bolt projecting from one member and loosely passing through an aperture in the other, and a 7 spring positioned on the projecting end of the bolt without the members whereby to normally hold the lugs in looking engagement with therecesses and to permit relative rotary movement of the members, substantially as and for the purpose described.

- 4. In a hinge construction for: automobile.v

Wind shields or guards, the combination of tWo cup shaped members one having a slightly smaller diameter than the other, and the peripheral flange of one member overlying and forming a housing for the periphery of the other member, the flange-of the inner member having in its free edge one or more recesses, and the inclosing member having one or more lugs projecting inaperture in the other, aspring positioned on the projecting end of the bolt Without the members whereby to normally hold the lugs in looking engagement with the recesses and to permit relative rotary movement of the members, a sleeve surrounding sa d sprlng and having a flange at its base to engage the outer surface ofone member, and a head at one end of the bolt against Which one end of the spring abuts, the head of the bolt constituting with the sleeve van inclosing housing for the spring, substantially as and for the purpose described.

In testimony whereof I have signed my name to this specification inthe presence of two subscribing Witnesses.
